Description
Product Name : 1336S-MCB Allen Braley Central control module
Product details:
The Allen-Bradley 1336S-MCB is a critical internal component for the 1336 PLUS series of Adjustable Frequency AC Drives. Specifically, it is the Main Control Board (MCB) that acts as the “brain” of the drive, executing control algorithms and managing communication between the user interface and the power hardware.
Product Overview
The 1336S-MCB is a microprocessor-based PCB (Printed Circuit Board) designed to replace or upgrade the control logic in Allen-Bradley 1336 PLUS drives. It regulates motor speed, torque, and direction by processing inputs and generating PWM (Pulse Width Modulation) signals for the power module.

Product Advantages
- Modular Design: Allows for easy field replacement, reducing the Mean Time to Repair (MTTR) for critical machinery.
- High Precision Control: Provides exceptional accuracy in motor speed regulation and torque response.
- Scalability: The same base board architecture is used across a wide range of drive power ratings within the 1336 PLUS family.
- Self-Diagnostics: Equipped with onboard logic to detect faults (e.g., overvoltage, overcurrent, or communication loss) to protect the motor and drive.
Critical Precautions & Maintenance
Warning: Dealing with Variable Frequency Drives involves high voltage. Only qualified personnel should handle this component.
- Electrostatic Discharge (ESD): This board is highly sensitive to static. Use an ESD wrist strap and grounded mat during installation to prevent permanent “silent” damage.
- Capacitor Discharge: Ensure the drive’s DC Bus capacitors have fully discharged before opening the chassis. Wait at least 5–10 minutes after disconnecting power and verify with a voltmeter.
- Firmware Matching: When replacing an MCB, ensure the firmware version is compatible with your existing Human Interface Module (HIM) and communication cards.
- Parameter Backup: Replacing the board will reset the drive to factory defaults. Always back up your parameters to a HIM module or PC before removal.
Product Applications
The 1336S-MCB is found in heavy-industrial environments where precise motor control is required:
- Conveyor Systems: Managing smooth start/stop transitions to prevent product damage.
- HVAC Systems: Controlling large centrifugal fans and pumps for energy efficiency.
- Material Handling: Used in cranes and hoists for steady torque control.
- Extruders and Mixers: Maintaining constant speed under varying load conditions in plastic and food processing.
